-"""lint_bp_context_emit_match — Tier 2f per internal#350.
-
-Rule
-----
-For a given protected branch, every context in
-`branch_protections/<branch>.status_check_contexts` MUST be emitted
-by at least one workflow in `.gitea/workflows/*.yml`. Two contexts
-match when:
-
-  1. The workflow's `name:` equals the context's workflow-part (the
-     prefix before ` / `).
-  2. Some job in that workflow has a `name:` (or default-fallback
-     job-key) equal to the context's job-part (between ` / ` and
-     ` (`).
-  3. The workflow's `on:` block includes the context's event-part
-     (in parens at the end), with Gitea's event-name mapping:
-        - `pull_request` and `pull_request_target` BOTH emit
-          `(pull_request)` contexts (verified empirically on
-          molecule-core/main).
-        - `push` emits `(push)`.
-
-A BP context with no emitter blocks merges forever — Gitea treats
-absent-as-`pending`, NOT absent-as-`skipped`-as-`success`. This is
-the phantom-required-check class
-(`feedback_phantom_required_check_after_gitea_migration`).
-
-The inverse direction (emitter without BP context) is INFORMATIONAL
-only — Tier 2g handles that direction at PR-time. Flagging it here
-on a daily schedule would falsely surface every transitional state
-during a BP rollout.
-
-How the gate works
-------------------
-Daily scheduled run + workflow_dispatch:
-
-  1. GET `branch_protections/{BRANCH}` (needs DRIFT_BOT_TOKEN with
-     repo-admin scope; same persona as ci-required-drift.yml).
-     Graceful-degrade on 403/404 per Tier 2a contract.
-
-  2. Walk `.gitea/workflows/*.yml` via PyYAML AST. For each workflow,
-     enumerate its emitted contexts: `{workflow.name} / {job.name or
-     job-key} ({event})` for each event in `on:` that emits a status.
-
-  3. For each BP context, look for an emitter match. Aggregate
-     orphans.
-
-  4. If orphans exist:
-     - File or PATCH a `[ci-bp-drift]` issue (idempotency contract:
-       search for exact title prefix, edit existing if open).
-     - Apply labels `tier:high` + `ci-bp-drift` (lookup IDs per
-       repo; per `feedback_tier_label_ids_are_per_repo`).
-     - Exit 1.
-
-  5. If no orphans:
-     - Close any existing `[ci-bp-drift]` issue with a clean-state
-       comment.
-     - Exit 0.
-
-Exit codes
-----------
-  0 — clean OR API 403/404 (graceful-degrade, surfaces ::error::).
-  1 — at least one BP context has no emitter.
-  2 — env contract violation, workflows-dir missing, or YAML parse
-      error.
-
-Env

-  GITEA_TOKEN     — DRIFT_BOT_TOKEN (repo-admin for branch_protections)
-  GITEA_HOST      — e.g. git.moleculesai.app
-  REPO            — owner/name
-  BRANCH          — defaults to `main`

-
-Rule
-----
-When a PR adds a NEW commit-status emission (a context that didn't
-exist on the base side), the workflow file must carry one of three
-directive comments adjacent to the new job:
-
-  (a) `# bp-required: yes`
-      The new context MUST already be in
-      `branch_protections/<branch>.status_check_contexts`. Verified
-      via Gitea API at PR time.
-
-  (b) `# bp-required: pending #NNN`
-      Acknowledged asymmetry; references an OPEN tracking issue that
-      will follow up with the BP PATCH.
-
-  (c) `# bp-exempt: <free-text reason>`
-      Informational job, not intended to be a required gate.
-
-No directive on a new emitter → FAIL with a 3-option fix-hint.
-
-The class this prevents
------------------------
-PR#656 added `CI / all-required (pull_request)` as a sentinel context
-that workflows emit, but BP did NOT list it. When `platform-build`
-failed, `all-required` failed, but BP let the PR merge anyway →
-cascade to mc#664. With this lint, PR#656 would have been blocked
-until either the BP PATCH ran alongside OR the author added a
-`bp-required: pending` directive.
-
-Why directives MUST live in the workflow YAML
----------------------------------------------
-The directive comment lives with the emitter so a scheduled
-audit (Tier 2f, daily) can read the same source. PR-body-only
-directives invisibly evaporate on merge — the asymmetry would
-return to undetected. PR-body claims are advisory; workflow-file
-comments are the contract.
-
-How "new emission" is detected
-------------------------------
-Diff base..head over `.gitea/workflows/*.yml`. For each YAML file
-that's added or modified:
-  - Parse both base-side and head-side via PyYAML AST.
-  - Enumerate emitted contexts on each side using the same rules as
-    Tier 2f (workflow.name + job.name|key + event-mapping).
-  - `new_contexts = head_contexts - base_contexts`.
-
-If `new_contexts` is empty after de-dup, no rule applies → pass.
-
-Per `feedback_behavior_based_ast_gates`: comment scanning uses raw
-text in a small window around the job-key line, NOT regex over the
-full file. This avoids matching `bp-required:` mentioned in a
-comment unrelated to the new job.
-
-Exit codes
-----------
-  0 — no new emissions, all new emissions have valid directives,
-      or BP read errored (graceful-degrade per Tier 2a contract).
-  1 — at least one new emission lacks a directive, or has
-      `bp-required: yes` but the context is missing from BP.
-  2 — env contract violation or YAML parse error.
-

-    source today is direct DB access (`mol_action_status` on op-host,

-

+#
+# RFC#351 Step 2 of 6 — implementation MVP. Tests cover:
+#   - slug normalization (the 4 example variants in the script header)
+#   - parse_directives (ack, revoke, with/without note, mid-comment, etc.)
+#   - section_marker_present (empty answer rejected, filled answer ok)
+#   - compute_ack_state (self-ack rejected, team probe applied, revoke
+#     invalidates own prior ack, peer's ack survives unrevoked)
+#   - render_status (state + description format)
+#   - get_tier_mode (label-driven, default fallback)
+#   - load_config (default config parses cleanly with both PyYAML and
+#     the bundled minimal parser)
+#
+# All tests run WITHOUT touching the Gitea API — the team-probe
+# callable is dependency-injected.

-# WHY A DEDICATED WORKFLOW (not folded into e2e-staging-saas.yml)
-# --------------------------------------------------------------
-# This is the systemic fix for a real trust failure. Hermes and OpenClaw
-# were reported "fleet-verified / cascade-complete" because the *proxy*
-# signals were green (registry registration + heartbeat for Hermes; model
-# round-trip 200 for OpenClaw). A freshly-provisioned workspace asked on
-# canvas "can you see your peers" actually FAILS:
-#   - Hermes: 401 on the molecule MCP `list_peers` call
-#   - OpenClaw: native `sessions_list` fallback, sees no platform peers
-# Tasks #142/#159 were even marked "completed" under this proxy flaw.
-#
-# A dedicated workflow (vs extending e2e-staging-saas.yml) because:
-#   - It must provision MULTIPLE distinct runtimes (hermes, openclaw,
-#     claude-code) in ONE org and assert each sees the others. The
-#     full-saas script is single-runtime-per-run (E2E_RUNTIME) and folding
-#     a multi-runtime matrix into it would conflate concerns and bloat its
-#     already-45-min run.
-#   - It needs its own concurrency group so it doesn't fight full-saas /
-#     canvas for the staging org-creation quota.
-#   - It needs an independent, non-required status-context name so it can
-#     be RED today (the in-flight Hermes-401 / OpenClaw-MCP-wiring fixes
-#     have not landed) WITHOUT wedging unrelated merges — and flipped to
-#     REQUIRED in one branch-protection edit once it goes green
-#     (flip-to-required checklist: molecule-core#1296).
-#
-# THE ASSERTION IS NOT A PROXY. The driving script
-# tests/e2e/test_peer_visibility_mcp_staging.sh issues the byte-for-byte
-# JSON-RPC `tools/call name=list_peers` envelope to `POST
-# /workspaces/:id/mcp` using each workspace's OWN bearer token, through
-# the real WorkspaceAuth + MCPRateLimiter middleware chain — the exact
-# call mcp_molecule_list_peers makes from a canvas agent. It does NOT
-# read a registry row, /health, the heartbeat table, or
-# GET /registry/:id/peers.
-#
-# HONEST GATE — NO continue-on-error. Per feedback_fix_root_not_symptom a
-# fake-green mask would defeat the entire purpose. This workflow goes red
-# on today's broken behavior and green only when the root-cause fixes
-# actually land. It is intentionally NOT in branch_protections — see PR
-# body for the required-vs-not decision + flip tracking issue.
-#
-# Gitea 1.22.6 / act_runner notes honored:
-#   - No cross-repo `uses:` (feedback_gitea_cross_repo_uses_blocked). The
-#     actions/checkout SHA is the one e2e-staging-canvas.yml already uses
-#     successfully (a mirrored SHA — see #1277/PR#1292 root-cause).
-#   - 2026-05-21 retrigger: verify fresh platform-tenant image after the
-#     publish Buildx DOCKER_CONFIG fix restored staging-latest image updates.
-#   - Per-SHA concurrency, not global (feedback_concurrency_group_per_sha).
-#   - Workflow-level GITHUB_SERVER_URL pinned
-#     (feedback_act_runner_github_server_url).
-#   - pr-validate posts a status under the same check name so a
-#     workflow-only PR is not silently statusless and the context is
-#     flip-to-required-ready (mirrors e2e-staging-saas.yml's proven shape;
-#     real EC2-provisioning E2E is push/dispatch/cron only — it is 30+ min
-#     and cannot run per-PR-update).
-#
-# LOCAL BACKEND (added 2026-05-15 — feedback_local_must_mimic_production,
-# feedback_mandatory_local_e2e_before_ship, feedback_local_test_before_
-# staging_e2e)
-# --------------------------------------------------------------------
-# The standing rule is that the local prod-mimic stack runs a MANDATORY
-# local-Postgres E2E BEFORE staging E2E. A staging-only peer-visibility
-# gate caught regressions late + expensively (cold EC2). The
-# `peer-visibility-local` job below runs the SAME byte-identical
-# assertion (tests/e2e/lib/peer_visibility_assert.sh) against the local
-# docker-compose stack — built + booted exactly like e2e-api.yml's
-# proven E2E API Smoke Test job (ephemeral pg/redis ports, go build,
-# background platform-server). It runs on PR + push (local boot is
-# minutes, not the 30+ min cold-EC2 path), so peer-visibility is part of
-# the local gate that fires before the staging E2E.
-#
-# It is its OWN non-required status context `E2E Peer Visibility (local)`.
-# The local backend uses external-mode workspaces by default so it tests
-# the literal platform MCP list_peers path without depending on local
-# template container boot/heartbeat. Container-mode runtime boot remains
-# available via PV_LOCAL_PROVISION_MODE=container for targeted debugging.

-# Tier 2f scheduled lint (per mc#774) — detects drift between
-# `branch_protections/<branch>.status_check_contexts` and the set of
-# contexts emitted by `.gitea/workflows/*.yml`.
-#
-# Rule
-# ----
-# For each protected branch context (Source A — BP), there must exist
-# at least one emitting workflow + job pair (Source B — workflow YAML
-# + on:-event mapping) whose runtime status-name maps to it. The
-# inverse direction (emitter without BP context) is informational
-# only — Tier 2g handles that at PR-time.
-#
-# Why this exists
-# ---------------
-# A BP-required context with no emitter blocks merges forever — Gitea
-# 1.22.6 treats absent-as-`pending`, NOT absent-as-`skipped`. The
-# phantom-required-check class previously surfaced as
-# `feedback_phantom_required_check_after_gitea_migration` (a port
-# kept the GitHub context name after rename to Gitea, but no
-# workflow emitted under the new name).
-#
-# This lint catches the same class structurally + a forward case:
-# workflow renamed/deleted while still in BP.
-#
-# Scope
-# -----
-# Scheduled daily. We DON'T run on `pull_request` because (a) the
-# emitter side moves with PR diffs (transitional state false-flags)
-# and (b) Tier 2g handles emitter-side drift at PR-time.
-#
-# Cross-repo
-# ----------
-# Today this runs only on molecule-core/main. Per internal#349
-# (cross-repo BP sweep) Class-D repos will get the same lint after
-# their BP rollouts.
-#
-# Auth
-# ----
-# `GET /repos/.../branch_protections/{branch}` requires repo-admin
-# role on Gitea 1.22.6. We use DRIFT_BOT_TOKEN (same persona as
-# ci-required-drift.yml — `internal#329` provisioning trail).
-# Graceful-degrade per Tier 2a contract: 403/404 → exit 0 with
-# ::error::.
-#
-# Idempotency
-# -----------
-# The drift issue is filed with title prefix
-# `[ci-bp-drift] {repo}/{branch}: BP→emitter mismatch`. The script
-# searches OPEN issues for an exact title-prefix match and PATCHes
-# the existing issue (if any) instead of POSTing a duplicate.
-# Mirrors `ci-required-drift.py`'s contract.
-#
-# Phase contract (RFC internal#219 §1 ladder)
-# -------------------------------------------
-# Lands at `continue-on-error: true` (Phase 3). After 7 days of clean
-# scheduled runs on `main`, flip to `false` so a scheduled failure
-# becomes a hard CI signal.

-name: Lint no tenant GITEA or GITHUB token write
-
-# Task #146 — CI guardrail companion to RFC#523's `lint-forbidden-env-keys.yml`.
-#
-# `lint-forbidden-env-keys.yml` (Layer 3) catches code that hardcodes a
-# forbidden env-var key NAME as a quoted literal in workspace_secrets
-# writer paths under workspace-server/internal/.
-#
-# This workflow catches a BROADER class: any code path that reads a
-# repo-host token (GITEA_TOKEN / GITHUB_TOKEN / GH_TOKEN) and then writes
-# it into a TENANT WORKSPACE's env, secret store, user-data, or
-# provision payload. This is the actual RFC#523 threat-model statement —
-# the goal is "no tenant workspace ever receives an operator-scope repo
-# token," not just "no _quoted_ literal `GITEA_TOKEN`." A future writer
-# could route the value via a variable, a struct field, or a config key
-# and slip past the existing literal scan; this lint catches those
-# routing patterns at PR review time.
-#
-# Scope
-#   Scans the WHOLE repo's Go sources (not just workspace-server/) for
-#   co-occurrences of:
-#     - a repo-host token NAME (GITEA_TOKEN / GITHUB_TOKEN / GH_TOKEN /
-#       GITEA_PAT / GITHUB_PAT) used as os.Getenv argument or string
-#       literal
-#     - within a file that ALSO references a tenant-writer surface
-#       (`tenant`, `workspace_secrets`, `global_secrets`, `seedAllowList`,
-#       `/settings/secrets`, `userData`, `provisionPayload`,
-#       `envVars[`, `containerEnv`).
-#
-#   Co-occurrence (not single-line) is the false-positive control: a
-#   file that just LOGS the variable name (e.g. "missing GITEA_TOKEN")
-#   without touching any tenant surface won't fire.
-#
-# Drift contract with lint-forbidden-env-keys.yml
-#   Both lints share the same FORBIDDEN_KEYS list (a subset — only the
-#   repo-host tokens, since this lint's threat model is "tenant gets
-#   write access to operator's git host"). If RFC#523's deny set grows,
-#   update BOTH this file AND lint-forbidden-env-keys.yml AND the Go
-#   source-of-truth in
-#   workspace-server/internal/handlers/workspace_provision_forbidden_env.go.
-#
-# Open-source-template-friendly
-#   The patterns scanned are generic (no MOLECULE_-prefix literals).
-#   A fork can copy this workflow as-is and adjust FORBIDDEN_KEYS.
-#
-# Path-filter discipline
-#   No `paths:` filter — required-status workflows must run on every PR
-#   per `feedback_path_filtered_workflow_cant_be_required`. Scan is
-#   sub-second.

-# Tier 2g hard-gate lint (per mc#774) — diff-based PR-time
-# check. When a PR adds a NEW commit-status emission (workflow YAML
-# `name:` + job `name:`-or-key + on:-event), the workflow file must
-# carry one of three directives adjacent to the new job:
-#
-#   - `# bp-required: yes`           — and BP must list the context
-#   - `# bp-required: pending #NNN`  — acknowledged asymmetry + tracker
-#   - `# bp-exempt: <reason>`        — informational job, not a gate
-#
-# Default (no directive on a new emitter) = FAIL.
-#
-# Why this exists
-# ---------------
-# PR#656 added `CI / all-required (pull_request)` as a sentinel
-# context that workflows emit, but BP did NOT list it. When
-# platform-build failed, all-required failed, but BP let the PR
-# merge anyway → cascade to mc#774. With this lint, PR#656 would
-# have been blocked until either the BP PATCH ran alongside OR
-# the author added a `bp-required: pending` directive.
-#
-# Tier 2g vs Tier 2f
-# ------------------
-# Tier 2g runs at PR-time (diff-based) and BLOCKS the merge.
-# Tier 2f runs daily (scheduled) and FILES a drift issue. They
-# share the workflow-context enumeration helpers
-# (`_event_map`, `workflow_contexts`, `_job_display`) but the
-# semantics are intentionally distinct so they're separate scripts.
-# Co-design is documented in mc#774.
-#
-# Directive comment lives in the workflow file (NOT PR body)
-# ----------------------------------------------------------
-# A PR-body claim of "BP exempt" evaporates on merge — the
-# asymmetry returns to undetected state and Tier 2f's daily
-# scheduled audit can't see it. The directive must live with the
-# emitter so both PR-time (Tier 2g) and post-merge (Tier 2f)
-# readers consume the same source.

-# Fail-closed lint that catches workflows touching docker.sock without
-# pinning `runs-on:` to a Linux-only label.
-#
-# Class defect (internal#512 + mc#1529 + today's oc#81/82/83 + autogen#8):
-# the `ubuntu-latest` label is advertised by BOTH the Linux operator-host
-# runners (molecule-runner-*) AND the Windows act_runner v1.0.3 on
-# hongming-pc-runner-*. Job placement is non-deterministic. When a docker-
-# bound job lands on a Windows runner, `docker run`/`docker login`/
-# `docker compose` fail with platform-specific errors ("protocol not
-# available", "cannot exec", etc.) — placement-dependent, not transient.
-#
-# This lint enforces the convention: any workflow whose YAML body
-# contains a docker exec (`docker run|build|buildx|compose|pull|push|
-# exec|tag|login|cp|inspect|ps` OR `docker/build-push-action|docker/
-# login-action|docker/setup-buildx`) MUST pin every job's `runs-on:` to
-# one of:
-#   - docker-host  (general docker.sock work — molecule-runner-*)
-#   - publish      (image build/push — molecule-runner-publish-*)
-#
-# Comments and heredoc/markdown bodies that merely MENTION docker are
-# excluded by the detection rule (see scan.py below).
-#
-# Per `feedback_never_skip_ci`: this is fail-closed (exit 1 on miss).

+# Auto-bump-on-workspace-edit half of the publish pipeline.
+#
+# Why this file exists (issue #351):
+#   Gitea Actions does not correctly disambiguate `paths:` from `tags:`
+#   when both are bundled under a single `on.push` key. The result is
+#   that tag pushes get filtered out and `publish-runtime.yml` never
+#   fires — `action_run` rows: 0. This was unnoticed pre-2026-05-11
+#   because PYPI_TOKEN was absent (publishes would have failed anyway).
+#
+#   Split design:
+#     - publish-runtime.yml         : on.push.tags only        (the publisher)
+#     - publish-runtime-autobump.yml: on.push.branches+paths   (this file — the version-bumper)
+#
+#   This file computes the next version from PyPI's latest, pushes a
+#   `runtime-v$VERSION` tag, and exits. The tag push then triggers
+#   publish-runtime.yml via its tags-only trigger.
+#
+# Concurrency: shares the `publish-runtime` group with publish-runtime.yml
+# so concurrent workspace pushes serialize at the bump step. Without
+# this, two pushes minutes apart could both read PyPI latest=0.1.129
+# and try to tag 0.1.130 simultaneously, only one of which would land.

+# Gitea Actions port of .github/workflows/publish-runtime.yml.

+# Ported 2026-05-10 (issue #206). Key differences from the GitHub version:
+#   - Gitea Actions reads .gitea/workflows/, not .github/workflows/
+#   - Dropped `environment: pypi-publish` — Gitea Actions does not support
+#     named environments or OIDC trusted publishers
+#   - Replaced `pypa/gh-action-pypi-publish@release/v1` (OIDC) with
+#     `twine upload` using PYPI_TOKEN secret — same mechanism as a local
+#     `python -m twine upload` with a PyPI token
+#   - Replaced `github.ref_name` (GitHub-only) with `${GITHUB_REF#refs/tags/}`
+#     — Gitea Actions exposes github.ref (the full ref) but not ref_name
+#   - Dropped `merge_group` trigger (Gitea has no merge queue)
+#
+# 2026-05-10 (issue #348): originally restored `staging`/`main` branch +
+# `workspace/**` path-filter trigger in PR #349.
+#
+# 2026-05-11 (issue #351): REVERTED the branches+paths trigger from THIS
+# file. Bundling `paths` with `tags` under a single `on.push` key caused
+# Gitea Actions to never dispatch the workflow for tag-push events (0
+# runs in `action_run` for workflow_id='publish-runtime.yml' since the
+# port, including the runtime-v1.0.0 tag — which is why PyPI is still at
+# 0.1.129 despite a v1.0.0 Gitea tag existing).
+#
+# The auto-bump-on-workspace-edit trigger now lives in
+# `.gitea/workflows/publish-runtime-autobump.yml`. That file computes the
+# next version from PyPI's latest and pushes a `runtime-v$VERSION` tag,
+# which THIS file then picks up via the tags-only trigger below.
+#
+# This decoupling means Gitea's path-vs-tag evaluator never has to
+# disambiguate — each file has a single unambiguous trigger shape.
+#
+# PyPI publishing: requires PYPI_TOKEN repository secret (or org-level secret).
+# Set via: repo Settings → Actions → Variables and Secrets → New Secret.
+# The token should be a PyPI API token scoped to molecule-ai-workspace-runtime.

+# it uses the Gitea API directly and was already Gitea-compatible.

+# sop-checklist-gate — peer-ack merge gate for SOP-checklist items.
+#
+# RFC#351 Step 2 of 6 (implementation MVP).
+#
+# === DESIGN ===
+#
+# Goal: each PR must answer 7 SOP-checklist questions in its body,
+# and each item must have at least one /sop-ack <slug> comment from
+# a non-author peer in the required team. BP requires the
+# `sop-checklist / all-items-acked (pull_request)` status to merge.
+#
+# Triggers:
+#   - `pull_request_target`: opened, edited, synchronize, reopened
+#       → fires when PR opens, body is edited (refire — RFC#351 §4),
+#         or new code is pushed (head.sha changes → stale status would
+#         be auto-discarded by BP via dismiss_stale_reviews, but the
+#         status itself is per-SHA so we re-post on the new head).
+#   - `issue_comment`: created, edited, deleted
+#       → fires on any new comment so /sop-ack / /sop-revoke take
+#         effect immediately (Gitea 1.22.6 doesn't refire on
+#         pull_request_review per feedback_pull_request_review_no_refire,
+#         so issue_comment is the canonical refire channel).
+#
+# Trust boundary (mirrors RFC#324 §A4 + sop-tier-check security note):
+#   `pull_request_target` (not `pull_request`) — workflow def is loaded
+#   from BASE branch, so a PR cannot rewrite this workflow to exfiltrate
+#   the token. The `actions/checkout` step pins `ref: base.sha` so the
+#   script ALSO comes from BASE. PR-HEAD code is never executed in the
+#   runner.
+#
+# Token scope:
+#   - read:repository, read:organization for PR + comments + team probes
+#   - write:repository for POST /statuses/{sha}
+#   - The token owner MUST be a member of every team referenced by the
+#     config's required_teams (else /teams/{id}/members/{login} returns
+#     403 — see review-check.sh same-gotcha doc). For the MVP we use
+#     the dev-lead token (a member of engineers, managers, qa, security)
+#     via a repo secret `SOP_CHECKLIST_GATE_TOKEN`. Provisioning of that
+#     secret is a follow-up authorization step (separate from this PR).
+#
+# Failure mode: tier-aware (RFC#351 open question 2):
+#   - tier:high   → state=failure (hard-fail; BP blocks merge)
+#   - tier:medium → state=failure (hard-fail; same)
+#   - tier:low    → state=pending (soft-fail; BP can choose to require
+#                    this context or skip for low-tier PRs)
+#   - missing/no-tier → state=failure (default-mode: hard — never lower
+#                    the bar per feedback_fix_root_not_symptom)
+#
+# Slash-command contract (RFC#351 v1 + §A1.1-style notes from RFC#324):
+#
+#   /sop-ack <slug-or-numeric-alias> [optional note]
+#       — register a peer-ack for one checklist item.
+#       — slug accepts kebab-case, snake_case, or natural-spaces
+#         (all normalize to canonical kebab-case).
+#       — numeric 1..7 maps via config.items[*].numeric_alias.
+#       — most-recent (user, slug) directive wins.
+#
+#   /sop-revoke <slug-or-numeric-alias> [reason]

-# RFC#351 Step 2 of 6 (implementation MVP).
-#
-# === CONSOLIDATION (issue #1280) ===
-#
-# This workflow is the SINGLE `issue_comment` subscriber — the logic from
-# `review-refire-comments.yml` has been merged in. Before this change:
-#   - sop-checklist.yml (pre-2026-05-16) → issue_comment:[created,edited,deleted] → runner slot used, job no-oped
-#   - review-refire-comments.yml           → issue_comment:[created]            → runner slot used, job no-oped
-#   → every non-refire comment occupied 2 runner slots for ~800 s each
-#      (~650 no-op runs/day, ~1,300 runner-slot-occupancy-hours/day).
-#
-# Fix (PR #1345 / issue #1280):
-#   - ONE workflow, ONE issue_comment:[created] subscription (no edited/deleted)
-#   - all-items-acked job: pull_request_target OR sop slash-command comments
-#   - review-refire job: qa/security/tier refire slash commands
-#   → ~50% reduction in comment-triggered runner occupancy vs pre-fix.

+# Runs the canary smoke suite against the staging canary tenant fleet
+# after a new :staging-<sha> image lands in ECR. On green, calls the
+# CP redeploy-fleet endpoint to promote :staging-<sha> → :latest so
+# the prod tenant fleet's 5-minute auto-updater picks up the verified
+# digest. On red, :latest stays on the prior known-good digest and
+# prod is untouched.
+#
+# Registry note (2026-05-10): This workflow previously used GHCR
+# (ghcr.io/molecule-ai/platform-tenant) — that registry was retired
+# during the 2026-05-06 Gitea suspension migration when publish-
+# workspace-server-image.yml switched to the operator's ECR org
+# (153263036946.dkr.ecr.us-east-2.amazonaws.com/molecule-ai/
+# platform-tenant). The GHCR → ECR migration was never applied to
+# this file, so canary-verify was silently smoke-testing the stale
+# GHCR image while the actual staging/prod tenants ran the ECR image.
+# Result: smoke tests could not catch a broken ECR build. Fix:
+#   - Wait step: reads SHA from running canary /health (tenant-
+#     agnostic, works regardless of registry).
+#   - Promote step: calls CP redeploy-fleet endpoint with target_tag=
+#     staging-<sha>, same mechanism as redeploy-tenants-on-main.yml.
+#     No longer attempts GHCR crane ops.
+#
+# Dependencies:
+#   - publish-workspace-server-image.yml publishes :staging-<sha>
+#     to ECR on staging and main merges.
+#   - Canary tenants are configured to pull :staging-<sha> from ECR
+#     (TENANT_IMAGE env set to the ECR :staging-<sha> tag).
+#   - Repo secrets CANARY_TENANT_URLS / CANARY_ADMIN_TOKENS /
+#     CANARY_CP_SHARED_SECRET are populated.

+
+# Hard gate (#2342): cron-driven full-lifecycle E2E that catches
+# regressions visible only at runtime — schema drift, deployment-pipeline
+# gaps, vendor outages, env-var rotations, DNS / CF / Railway side-effects.
+#
+# Why this gate exists:
+#   PR-time CI catches code-level regressions but not deployment-time or
+#   integration-time ones. Today's empirical data:
+#     • #2345 (A2A v0.2 silent drop) — passed all unit tests, broke at
+#       JSON-RPC parse layer between sender and receiver. Visible only
+#       to a sender exercising the full path.
+#     • RFC #2312 chat upload — landed on staging-branch but never
+#       reached staging tenants because publish-workspace-server-image
+#       was main-only. Caught by manual dogfooding hours after deploy.
+#   Both would have surfaced within 15-20 min of regression if a
+#   continuous synth-E2E was running.
+#
+# Cadence: every 20 min (3x/hour). The script is conservatively
+# bounded at 10 min wall-clock; even on degraded staging it should
+# finish before the next firing. cron-overlap is guarded by the
+# concurrency group below.
+#
+# Cost: ~3 runs/hour × 5-10 min × $0.008/min GHA = ~$0.50-$1/day.
+# Plus a fresh tenant provisioned + torn down each run (Railway +
+# AWS pennies). Negligible.
+#
+# Failure handling: when the run fails, the workflow exits non-zero
+# and GitHub's standard email/notification path fires. Operators
+# can subscribe to this workflow's failure channel for paging-grade
+# alerting.
+
+on:
+  schedule:
+    # Every 10 minutes, on :02 :12 :22 :32 :42 :52. Three constraints:
+    #   1. Stay off the top-of-hour. GitHub Actions scheduler drops
+    #      :00 firings under high load (own docs:
+    #      https://docs.github.com/en/actions/using-workflows/events-that-trigger-workflows#schedule).
+    #      Prior history: cron was '0,20,40' (2026-05-02) — only :00
+    #      ever survived. Bumped to '10,30,50' (2026-05-03) on the
+    #      theory that further-from-:00 wins. Empirically 2026-05-04
+    #      that ALSO dropped to ~60 min effective cadence (only ~1
+    #      schedule fire per hour — see molecule-core#2726). Detection
+    #      latency was claimed 20 min, actual 60 min.
+    #   2. Avoid colliding with the existing :15 sweep-cf-orphans
+    #      and :45 sweep-cf-tunnels — both hit the CF API and we
+    #      don't want to fight for rate-limit tokens.
+    #   3. Avoid the :30 heavy slot (canary-staging /30, sweep-aws-
+    #      secrets, sweep-stale-e2e-orgs every :15) — multiple
+    #      overlapping cron registrations on the same minute is part
+    #      of what GH drops under load.
+    # Solution: bump fires-per-hour 3 → 6 AND keep all slots in clean
+    # lanes (1-3 min away from any other cron). Even with empirically-
+    # observed ~67% GH drop ratio, 6 attempts/hour yields ~2 effective
+    # fires = ~30 min cadence; closer to the 20-min target than the

+# Trigger model (revised 2026-04-29):
+#
+# Always FIRES on push/pull_request to staging+main. Real work is gated
+# per-step on `needs.detect-changes.outputs.api` — when paths under
+# `workspace-server/`, `tests/e2e/`, or this workflow file haven't
+# changed, the no-op step alone runs and emits SUCCESS for the
+# `E2E API Smoke Test` check, satisfying branch protection without
+# spending CI cycles. See the in-job comment on the `e2e-api` job for
+# why this is one job (not two-jobs-sharing-name) and the 2026-04-29
+# PR #2264 incident that drove the consolidation.
+#
+# Parallel-safety (Class B Hongming-owned CICD red sweep, 2026-05-08)
+# -------------------------------------------------------------------
+# Same substrate hazard as PR #98 (handlers-postgres-integration). Our
+# Gitea act_runner runs with `container.network: host` (operator host
+# `/opt/molecule/runners/config.yaml`), which means:
+#
+#   * Two concurrent runs both try to bind their `-p 15432:5432` /
+#     `-p 16379:6379` host ports — the second postgres/redis FATALs
+#     with `Address in use` and `docker run` returns exit 125 with
+#     `Conflict. The container name "/molecule-ci-postgres" is already
+#     in use by container ...`. Verified in run a7/2727 on 2026-05-07.
+#   * The fixed container names `molecule-ci-postgres` / `-redis` (the
+#     pre-fix shape) collide on name AS WELL AS port. The cleanup-with-
+#     `docker rm -f` at the start of the second job KILLS the first
+#     job's still-running postgres/redis.
+#
+# Fix shape (mirrors PR #98's bridge-net pattern, adapted because
+# platform-server is a Go binary on the host, not a containerised
+# step):
+#
+#   1. Unique container names per run:
+#         pg-e2e-api-${RUN_ID}-${RUN_ATTEMPT}
+#         redis-e2e-api-${RUN_ID}-${RUN_ATTEMPT}
+#      `${RUN_ID}-${RUN_ATTEMPT}` is unique even across reruns of the
+#      same run_id.
+#   2. Ephemeral host port per run (`-p 0:5432`), then read the actual
+#      bound port via `docker port` and export DATABASE_URL/REDIS_URL
+#      pointing at it. No fixed host-port → no port collision.
+#   3. `127.0.0.1` (NOT `localhost`) in URLs — IPv6 first-resolve was
+#      the original flake fixed in #92 and the script's still IPv6-
+#      enabled.
+#   4. `if: always()` cleanup so containers don't leak when test steps
+#      fail.
+#
+# Issue #94 items #2 + #3 (also fixed here):
+#   * Pre-pull `alpine:latest` so the platform-server's provisioner
+#     (`internal/handlers/container_files.go`) can stand up its
+#     ephemeral token-write helper without a daemon.io round-trip.
+#   * Create `molecule-core-net` bridge network if missing so the
+#     provisioner's container.HostConfig {NetworkMode: ...} attach
+#     succeeds.
+# Item #1 (timeouts) — evidence on recent runs (77/3191, ae/4270, 0e/
+# 2318) shows Postgres ready in 3s, Redis in 1s, Platform in 1s when
+# they DO come up. Timeouts are not the bottleneck; not bumped.
+#
+# Item explicitly NOT fixed here: failing test `Status back online`
+# fails because the platform's langgraph workspace template image
+# (ghcr.io/molecule-ai/workspace-template-langgraph:latest) returns
+# 403 Forbidden post-2026-05-06 GitHub org suspension. That is a
+# template-registry resolution issue (ADR-002 / local-build mode) and
+# belongs in a separate change that touches workspace-server, not

+# Regression for the four/five workspaces.status=awaiting_agent transitions
+# that silently failed in production for five days before migration 046
+# extended the workspace_status enum (see
+# workspace-server/migrations/046_workspace_status_awaiting_agent.up.sql).
+#
+# Why this is its own workflow (not folded into e2e-staging-saas.yml):
+#   - The full-saas harness defaults to runtime=hermes, never exercises
+#     external-runtime. Adding an `external` parameter to that script
+#     would force every push to staging through both lifecycles in
+#     series, doubling the EC2 cold-start budget.
+#   - The external lifecycle has unique timing (REMOTE_LIVENESS_STALE_AFTER
+#     window, 90s default + sweep interval), which we wait through
+#     deliberately. Folding it into hermes would make the long path
+#     even longer.
+#   - It can run in parallel with the hermes E2E since both create
+#     fresh tenant orgs with distinct slug prefixes (`e2e-ext-...` vs
+#     `e2e-...`).
+#
+# Triggers:
+#   - Push to staging when any source affecting external runtime,
+#     hibernation, or the migration set changes.
+#   - PR review for the same set.
+#   - Manual workflow_dispatch.
+#   - Daily cron at 07:30 UTC (catches drift on quiet days; staggered
+#     30 min after e2e-staging-saas.yml's 07:00 UTC cron).
+#
+# Concurrency: serialized so two staging pushes don't fight for the
+# same EC2 quota window. cancel-in-progress=false so a half-rolled

+# Dedicated workflow that provisions a fresh staging org per run, exercises
+# the full workspace lifecycle (register → heartbeat → A2A → delegation →
+# HMA memory → activity → peers), then tears down and asserts leak-free.
+#
+# Why a separate workflow (not folded into ci.yml):
+#   - The run takes ~25-35 min (EC2 boot + cloudflared DNS + provision sweeps +
+#     agent bootstrap), way too slow for every PR.
+#   - Needs its own concurrency group so two pushes don't fight over the
+#     same staging org slug prefix.
+#   - Has its own required secrets (session cookie, admin token) that most
+#     PRs don't need to read.
+#
+# Triggers:
+#   - Push to main (regression guard)
+#   - workflow_dispatch (manual re-run from UI)
+#   - Nightly cron (catches drift even when no pushes land)
+#   - Changes to any provisioning-critical file under PR review (opt-in

+# Real-Postgres integration tests for workspace-server/internal/handlers/.
+# Triggered on every PR/push that touches the handlers package.
+#
+# Why this workflow exists
+# ------------------------
+# Strict-sqlmock unit tests pin which SQL statements fire — they're fast
+# and let us iterate without a DB. But sqlmock CANNOT detect bugs that
+# depend on the row state AFTER the SQL runs. The result_preview-lost
+# bug shipped to staging in PR #2854 because every unit test was
+# satisfied with "an UPDATE statement fired" — none verified the row's
+# preview field actually landed. The local-postgres E2E that retrofit
+# self-review caught it took 2 minutes to set up and would have caught
+# the bug at PR-time.
+#
+# Why this workflow does NOT use `services: postgres:` (Class B fix)
+# ------------------------------------------------------------------
+# Our act_runner config has `container.network: host` (operator host
+# /opt/molecule/runners/config.yaml), which act_runner applies to BOTH
+# the job container AND every service container. With host-net, two
+# concurrent runs of this workflow both try to bind 0.0.0.0:5432 — the
+# second postgres FATALs with `could not create any TCP/IP sockets:
+# Address in use`, and Docker auto-removes it (act_runner sets
+# AutoRemove:true on service containers). By the time the migrations
+# step runs `psql`, the postgres container is gone, hence
+# `Connection refused` then `failed to remove container: No such
+# container` at cleanup time.
+#
+# Per-job `container.network` override is silently ignored by
+# act_runner — `--network and --net in the options will be ignored.`
+# appears in the runner log. Documented constraint.
+#
+# So we sidestep `services:` entirely. The job container still uses
+# host-net (inherited from runner config; required for cache server
+# discovery on the bridge IP 172.18.0.17:42631). We launch a sibling
+# postgres on the existing `molecule-core-net` bridge with a
+# UNIQUE name per run — `pg-handlers-${RUN_ID}-${RUN_ATTEMPT}` — and
+# read its bridge IP via `docker inspect`. A host-net job container
+# can reach a bridge-net container directly via the bridge IP (verified
+# manually on operator host 2026-05-08).
+#
+# Trade-offs vs. the original `services:` shape:
+#   + No host-port collision; N parallel runs share the bridge cleanly
+#   + `if: always()` cleanup runs even on test-step failure
+#   - One more step in the workflow (+~3 lines)
+#   - Requires `molecule-core-net` to exist on the operator host
+#     (it does; declared in docker-compose.yml + docker-compose.infra.yml)
+#
+# Class B Hongming-owned CICD red sweep, 2026-05-08.

+# Why this exists: 2026-04-30 we shipped #2398 which added /buildinfo as

+# allowlist. The handler-level test in buildinfo_test.go constructed a

+# buildinfo-stale-image.sh replay would have caught it (cf-proxy doesn't
+# inject X-Molecule-Org-Id, so the curl path is identical to production's
+# redeploy verifier), but no one ran the harness pre-merge. The bug
+# shipped; the redeploy verifier silently soft-warned every tenant as

+# Daily audit of Railway env vars for drift-prone image-tag pins —
+# automation-cadence layer over the detection script + regression test
+# shipped in PR #2168 (#2001 closure).
+#
+# Background: on 2026-04-24 a stale `:staging-a14cf86` SHA pin in CP's
+# TENANT_IMAGE caused 3+ hours of E2E failure with the appearance that
+# "every fix didn't propagate" — really the tenant image was so old it
+# didn't read the env vars those fixes produced. The audit script
+# (scripts/ops/audit-railway-sha-pins.sh) flags drift; this workflow
+# runs the same check unattended on a daily cron.
+#
+# Cadence: once a day, 13:00 UTC (06:00 PT). Daily is the right
+# cadence for variables-tier config — Railway env var changes are
+# deliberate operator actions, low-frequency. Hourly would risk
+# Railway API rate-limit surprises and is overkill for the change rate.
+#
+# Issue-on-failure: drift triggers a priority-high issue, mirroring
+# .github/workflows/e2e-staging-sanity.yml's pattern. Drift is
+# medium-priority "config slipped, fix at next ops window," not
+# active-outage paging.
+#
+# Secret hardening: per feedback_schedule_vs_dispatch_secrets_hardening,
+# the schedule trigger HARD-FAILS on missing RAILWAY_AUDIT_TOKEN
+# (silent-success on schedule was the failure-mode class that bit the
+# team before; cron firing without checking anything is worse than no
+# cron). The workflow_dispatch trigger SOFT-SKIPS on missing secret so
+# an operator can dry-run the workflow shape during initial provisioning

+# Why this workflow exists: publish-workspace-server-image builds and
+# pushes a new platform-tenant :<sha> to ECR on every merge to main,
+# but running tenants pulled their image once at boot and never re-pull.
+# Users see stale code indefinitely.
+#
+# This workflow closes the gap by calling the control-plane admin
+# endpoint that performs a canary-first, batched, health-gated rolling
+# redeploy across every live tenant. Implemented in molecule-ai/
+# molecule-controlplane as POST /cp/admin/tenants/redeploy-fleet
+# (feat/tenant-auto-redeploy, landing alongside this workflow).
+#
+# Registry: ECR (153263036946.dkr.ecr.us-east-2.amazonaws.com/
+# molecule-ai/platform-tenant). GHCR was retired 2026-05-07 during the
+# Gitea suspension migration. The canary-verify.yml promote step now
+# uses the same redeploy-fleet endpoint (fixes the silent-GHCR gap).
+#
+# Runtime ordering:
+#   1. publish-workspace-server-image completes → new :staging-<sha> in ECR.
+#   2. This workflow fires via workflow_run, calls redeploy-fleet with
+#      target_tag=staging-<sha>. No CDN propagation wait needed —
+#      ECR image manifest is consistent immediately after push.
+#   3. Calls redeploy-fleet with canary_slug (if set) and a soak
+#      period. Canary proves the image boots; batches follow.
+#   4. Any failure aborts the rollout and leaves older tenants on the
+#      prior image — safer default than half-and-half state.
+#
+# Rollback path: re-run this workflow with a specific SHA pinned via

+# Auto-refresh staging tenant EC2s after every staging-branch merge.
+#
+# Mirror of redeploy-tenants-on-main.yml, with the staging-CP host and
+# the :staging-latest tag. Sister workflow exists for prod (rolls
+# :latest after canary-verify). Both share the same shape — just
+# different CP_URL + target_tag + admin token secret.
+#
+# Why this workflow exists: publish-workspace-server-image now builds
+# on every staging-branch push (PR #2335), pushing
+# platform-tenant:staging-latest to GHCR. Existing tenants pulled
+# their image once at boot and never re-pull, so the new image just
+# sits unused until the tenant is reprovisioned.
+#
+# This workflow closes the gap by calling staging-CP's
+# /cp/admin/tenants/redeploy-fleet, which performs a canary-first,
+# batched, health-gated SSM redeploy across every live staging tenant.
+# Same endpoint shape as prod CP — only the host differs.
+#
+# Runtime ordering:
+#   1. publish-workspace-server-image completes on staging branch →
+#      new :staging-latest in GHCR.
+#   2. This workflow fires via workflow_run, waits 30s for GHCR's CDN
+#      to propagate the new tag.
+#   3. Calls redeploy-fleet with no canary (staging IS canary; we don't
+#      need a sub-canary inside it). Soak still applies to the first
+#      tenant in case of bad-deploy detection.
+#   4. Any failure aborts the rollout and leaves older tenants on the
+#      prior image — safer default than half-and-half state.
+#
+# Rollback path: re-run with workflow_dispatch + target_tag=staging-<sha>
+# of a known-good build.
